1. Can gold be found by disassembling the AF-E400 flowmeter?

Disassembling the AF-E400 flowmeter is likely to result in no gold being found. The AF-E400 flowmeter belongs to industrial flow measurement equipment, and commonly used industrial materials such as plastic casing, metal fittings, and electronic components are commonly used in conventional manufacturing. Gold, as a high cost precious gold pure component, is generally not used in the production process of ordinary industrial flow meters. Only a very small number of customized equipment with special material functional requirements may use gold related components. Such scenarios are extremely rare.

2. Structure principle of metal tube float flowmeter

Metal tube float flowmeter is a commonly used flow measurement instrument, and its structure principle is as follows: Working principle: The float of the metal tube float flowmeter is placed in the measuring tube, and when the fluid flows through the measuring tube, the float will be subjected to the force of the fluid.

. As the flow rate changes, the float will move up and down inside the measuring tube. When the float moves to a certain position, the buoyancy it receives reaches an equilibrium state with its own gravity. At this point, a circulation gap will be formed between the float and the orifice plate (or cone tube), and the area of this gap will remain constant. And the annular gap area is directly proportional to the rising height of the float, that is, the position of the float rising in the measuring tube can represent the size of the flow rate. In order to transmit the position information of the float to indicate the flow value, a magnet is installed inside the float. The ch Gold flowmeter

ange in float position is transmitted to the external indicator through an internal magnet, allowing the indicator to correctly display the current flow rate value. This magnetic coupling transmission method eliminates the need for direct contact between the indicator housing and the measuring tube. Therefore, even with limit switches or transmitters installed, the instrument can still be used under high temperature and high pressure working conditions. The metal tube float flowmeter is mainly composed of two parts: the sensor measuring tube and the float. The measuring tube is a channel for fluid flow, and the float moves in it with the change of flow rate. The liquid receiving material of the sensor has multiple options, including stainless steel, Hastelloy, titanium, and PTFE lined stainless steel. Users can select suitable liquid receiving materials based on the pressure of the non imitation process and the corrosion resistance requirements of the medium, in order to meet the pressure resistance requirements of the process and the anti-corrosion requirements of the medium. For example, in highly corrosive chemical processes, corrosion-resistant materials such as Hastelloy or titanium can be chosen; In situations where general stainless steel can meet the requirements of pressure resistance and corrosion resistance, stainless steel material can be selected; For some media that have both certain pressure resistance requirements and special anti-corrosion requirements, stainless steel lined with PTFE is a good choice. Signal transmitter indicator: According to different measurement requirements, users can choose different indicator combinations when selecting, thereby achieving different measurement functions.
